L2TP VPN - Accessing local network without using gateway on vpn connection

Hi,

Thanks for your help on the previous issue i had. I have one last one that i need assistance with.

What rules do I need to set-up to allow access to my local network when i have unticked 'use default gateway' on the VPN connection. I believe its due to VPN IP and local LAN ip being on different subnets. Do i need a static route? Interface static route doesnt work

FYI - works fine when using default gateway

Rules i have setup within the firewall is;
L2TP VPN pool > any > internal
L2TP VPN Pool > web surfing > external
L2TP VPN Pool > ping > external
